IOS supports three levels of thread programming, from the underlying layer to the high-level (the higher the level, the more convenient to use, the more concise) are: 1: thread; 2: cocoa operations; 3: Grand Central Dispatch; Introduction: ThreadIt has the lowest abstraction level. The other two thread applications encapsulate thread. For programmers, thread is relatively troublesome and requires programmer

passed to normal view for processing. If your view does not handle an event, the event is passed to its parent view. Because the normal view does not handle events, it passes those events first to its view controller. If the view controller does not handle the event, then the event is further passed to the parent view of the normal UIView object, in this case the parent view is the Window object.Figure 7-1 Responder Chain for view controllersNote: The message-passing relationship between a view

Use the endIngnoringInteractionEvents method to restore events that are received and distributed by programs.If you want a view to receive multi-point touch, you need to set its multipleTouchEnabled attribute to YES. The default value is NO, that is, the view does not receive multi-point touch by default.In the previous iOS Programming-touch Event Processing (1), I learned how to handle t
